Definitions
- the present invention relates to an information processing device, an information processing system, and an information processing method.
- MFP is an abbreviation for a “multifunction peripheral”.
- Japanese Laid-open Patent Publication No. 2003-167703 discloses a job processing method performed by a printer for setting a priority order of execution appropriate for each print job to be processed when a plurality of print jobs are transmitted to one MFP.
- this job processing method printing operation time and the number of sheets to be printed are calculated for each print job. As a result of calculation, a priority is given to each print job. Accordingly, when the print jobs compete with each other in a printer device, an optimum order of priority can be determined to execute printing.
- MFPs in the related art that can be remotely controlled via a portable terminal device process a print job transmitted from the portable terminal device in the same way as a print job received via an operation panel installed in the MFP. For example, when a print job transmitted from the portable terminal device of a user at a place distant from the MFP has been received earlier than a print job of a user at a position near the MFP, the MFP processes the print job of the user at the distant position in preference to the print job of the user at the position near the MFP.
- the user at the position near the MFP needs to wastefully wait until the print job of the user at the distant position, who takes time to collect printed matter, is finished although the user near the MFP can immediately collect the printed matter.
- the priority of each print job is determined from a calculation result of the number of sheets to be printed and the printing operation time for each print job. Accordingly, similarly to the above case, there is a problem that the print job of the user at the distant place, who takes time to collect the printed matter, is executed earlier, and the user at the position near the MFP needs to wastefully wait for processing of the print job although he/she can immediately collect the printed matter.
- An information processing device includes: a storage processing unit that receives an information processing request transmitted from a terminal device and then stores the information processing request and a priority for executing the information processing request in a storage unit in association with each other; an information processing unit that executes information processing requests stored in the storage unit in order from an information processing request in association with which a higher priority is stored; a moving speed calculation unit that calculates a moving speed of the terminal device based on, out of positional information transmitted at predetermined timings from the terminal device that has transmitted the information processing request, first positional information transmitted at a first timing and second positional information transmitted at a second timing subsequent to the first positional information; a time calculation unit that calculates a time until a distance between the terminal device and the information processing device becomes equal to or smaller than a predetermined value based on the moving speed calculated by the moving speed calculation unit, positional information of the information processing device, and the second positional information; and a replacement processing unit that replaces, when a second time as a time until the distance between a second terminal device that has

- An information processing method is performed by an information processing device.
- the method includes: by a storage processing unit, receiving an information processing request transmitted from a terminal device and then storing the information processing request and a priority for executing the information processing request in a storage unit in association with each other; by an information processing unit, executing information processing requests stored in the storage unit in order from an information processing request in association with which a higher priority is stored; by a moving speed calculation unit, calculating a moving speed of the terminal device based on, out of positional information transmitted at predetermined timings from the terminal device that has transmitted the information processing request, first positional information transmitted at a first timing and second positional information transmitted at a second timing subsequent to the first positional information; by a time calculation unit, calculating a time until a distance between the terminal device and the information processing device becomes equal to or smaller than a predetermined value based on the moving speed calculated by the moving speed calculation unit, positional information of the information processing device, and the second positional information; and by a replacement processing unit, when a second time as

- a multifunction peripheral that can be remotely controlled by a portable terminal device acquires, at predetermined timings (for example, periodically), positional information of a portable terminal device that has transmitted a print job.
- the MFP detects a moving speed from the positional information of a user. If the print job of a user positioned near the MFP can be completed by the time when a user at a distant place comes to collect printed matter, the MFP processes the print job of the user at the near place in preference to the print job of the user at the distant place.
- the print job of the user near the MFP can be executed by the time when the user at a place distant from the MFP comes to collect the printed matter. Accordingly, the time until the user at the place distant from the MFP comes to collect the printed matter can be effectively utilized, the user near the MFP can be prevented from wastefully waiting, and efficient processing of the print job can be achieved.

- the CPU 16 operates as an example of a storage processing unit to add the priorities to the print jobs in a received order as illustrated in FIG. 5 , and controls the print jobs to be stored in the job DB 29 .

- the CPU 16 revises the priority according to the “distance”, the “collection time”, the “printing time”, and/or the like described above.
- the CPU 16 performs replacement processing for causing the print job to which a lower priority is given to have a higher priority.
- FIG. 5 illustrates a case in which a third print job having the third priority is replaced with a fourth print job having the fourth priority.
- FIGS. 6A and 6B are diagrams for explaining information used by the MFP 1 for replacing the priorities of printing.
- the MFP 1 periodically acquires the present position of the portable terminal device 2 or the like that has transmitted the print job using the ad hoc communication or the infrastructure communication as described above.
- the MFP 1 calculates the distance between the portable terminal device 2 and the MFP 1 based on the present position of the portable terminal device 2 or the like and the present position of the MFP 1 .
- the MFP 1 handles the calculated distance as a distance L to a sender (portable terminal device 2 ) of the print job.
- the MFP 1 periodically calculates the distance L to the sender (portable terminal device 2 ).
- a value obtained by dividing the moving distance M by a time (H 2 ⁇ H 1 ) between when the present positions of the portable terminal device 2 have been acquired is a moving speed V of the sender.
- a value obtained by dividing the distance L by the moving speed V is an estimated time T until the sender comes to collect the printed matter.
- the MFP 1 updates such pieces of information every time when acquiring the present position of the portable terminal device 2 , and adds the pieces of information to the corresponding print job to store them in the job DB 29 .
- the MFP 1 performs replacement determination of priorities of the print jobs using these pieces of information, the N-th priority of the print job, and a processing time C of the print job.
- the MFP 1 performs replacement processing of the priorities of the print jobs according to a result of the replacement determination.
- FIG. 7 is a diagram for explaining the replacement determination of the priorities of the print jobs.
- the MFP 1 processes the print jobs in the received order in principle. That is, the MFP 1 preferentially processes the print job that has been transmitted earlier. However, when it is estimated that the user that has transmitted the print job later will come to collect the printed matter earlier than the user that has transmitted the print job earlier (the former user will come to collect the printed matter in a short time), the MFP 1 performs processing of replacing the priorities of both print jobs. Due to this, the printed matter of the user that has transmitted the print job later can be printed in a time period until the user that has transmitted the print job earlier comes to collect the printed matter, so that efficient printing processing can be performed.
- the printed matter of the user that has transmitted the print job later may be printed in a time period until the user that has transmitted the print job earlier comes to collect the printed matter.
- the user that has transmitted the print job earlier inconveniently reaches the MFP 1 before printing corresponding to the earlier print job is completed.
- the user that has transmitted the print job earlier needs to wait in front of the MFP 1 until the printing corresponding to the print job of himself/herself is completed. Due to this, if the replacement processing of the priorities causes the user that has transmitted the print job earlier to wait, or causes a waiting time to be longer, the MFP 1 does not perform replacement processing of the priorities as described below. Accordingly, intelligent replacement processing is performed.
- a print collection time for a sender A of the print job is assumed to be “Ta”, and the print collection time for a sender B of the print job is assumed to be “Tb”.
- the priority of the sender A is assumed to be “Na”, and the priority of the sender B is assumed to be “Nb”.
- a printing processing time for the print job of the sender A is assumed to be “Ca”, and the printing processing time for the print job of the sender B is assumed to be “Cb”.
- the sender A having a higher priority needs to wait when the print job A and the print job B are processed.
- the MFP 1 does not perform processing of replacing the print job of the sender A with the print job of the sender B.
- the MFP 1 performs such replacement determination of the priorities and replacement processing of the priorities at a timing of updating the print job (timing of acquiring the present position of each portable terminal device or the like) between adjacent print jobs in the job DB 29 (print job queue).
- FIG. 8 is a flowchart illustrating a procedure of update processing of the print job stored in the job DB 29 in the RAM 18 .
- the CPU 16 of the MFP 1 reads the printing processing program stored in the HDD 19 to load the components 21 to 26 illustrated in FIG. 2 on the RAM 18 and causes the components to function.
- Step S 1 the check unit 21 illustrated in FIG. 2 checks the number of the print jobs stored in the job DB 29 in the RAM 18 . If the number of the print jobs stored in the job DB 29 is “0” (the number of the print jobs >0), the process proceeds to Step S 11 .
- the standby processing unit 26 counts the time being kept by the timer 15 illustrated in FIG. 1 corresponding to the time allocated as an interval (Int) between pieces of update processing of the print job to cause the update processing to be in a standby state. When the time corresponding to the interval is counted, the update processing returns to Step S 1 , and the check unit 21 checks the number of the print jobs stored in the job DB 29 again.
- the position acquisition unit 22 sets a number for designating the portable terminal device 2 (or the personal computer device 3 ) the present position of which is acquired to be “1” (N ⁇ 1).
- the MFP 1 sequentially performs update processing from the print job having the first priority. Due to this, in performing update processing for the first time, information of “N ⁇ 1” is stored in the RAM 18 or the like for designating the update processing of the print job having the first priority.
- the position acquisition unit 22 acquires the present position of the portable terminal device 2 or the like that has transmitted the print job having the priority corresponding to the set number N. Specifically, when having received a print request from the portable terminal device 2 , the MFP 1 issues unique identification information to the portable terminal device 2 together with a message that the print request has been received.
- the CPU 34 of each portable terminal device 2 illustrated in FIG. 3 After transmitting the print job to the MFP 1 , the CPU 34 of each portable terminal device 2 illustrated in FIG. 3 detects the present position of itself via the GPS 33 every predetermined time (every interval time described above) according to the printing processing program stored in the HDD 37 . The CPU 34 of the portable terminal device 2 then adds the identification information issued from the MFP 1 to the detected present position of itself, and transmits the information to the MFP 1 via the communication unit 31 .
- the position acquisition unit 22 of the MFP 1 acquires, at Step S 3 , the present position of each portable terminal device 2 that is periodically transmitted from the portable terminal device 2 or the like.
- the moving speed calculation unit 23 performs an operation of Expression 1 as follows to calculate the moving speed “MN” of the portable terminal device 2 assuming that the position of the portable terminal device 2 acquired in the last time is “PN ⁇ 1”, the currently acquired present position of the same portable terminal device 2 is “PN”, and the interval for performing update processing is “Int”.
- Step S 5 the position acquisition unit 22 acquires a present position PMF of the MFP 1 via the GPS 14 illustrated in FIG. 3 .
- Step S 6 it is determined whether the position acquisition unit 22 has acquired the present position PMF of the MFP 1 . If it is determined that the present position PMF has been acquired (Yes at Step S 6 ), the process proceeds to Step S 8 . If it is determined that the position acquisition unit 22 cannot acquire the present position PMF of the MFP 1 (No at Step S 6 ), the process proceeds to Step S 7 .
- the position acquisition unit 22 reads out and acquires the present position of the MFP 1 that is detected by the GPS 14 in advance and stored in the storage unit such as the RAM 36 and the HDD 37 because the GPS 14 cannot acquire the present position PMF of the MFP 1 .
- the position acquisition unit 22 reads out and acquires the present position of the MFP 1 that is stored in the storage unit such as the RAM 36 and the HDD 37 in advance via the operation unit 13 or the like by the user.
- the collection time calculation unit 24 performs an operation of Expression 2 as follows to calculate a collection time “TN” until the user of the portable terminal device 2 comes to collect the printed matter assuming that the moving speed of the portable terminal device 2 is “MN”, the currently acquired present position of the portable terminal device 2 is “PN”, and the present position of the MFP 1 is “PMF”.
- the collection time “TN” is an example of a time until the distance between the MFP 1 and the portable terminal device 2 becomes equal to or smaller than a predetermined value.
- Step S 9 the check unit 21 determines whether the print job having the (N+1)-th priority is present in the job DB 29 . In other words, the check unit 21 determines whether another print job the update processing on which should be examined is stored in the job DB 29 . If it is determined that the other print job is stored (Yes at Step S 9 ), at Step S 12 , the check unit 21 increments a current number for designating the update processing of the print job by one to shift the print job the update processing on which should be examined to the print job having the next priority. That is, “1” is added to the current number for designating the update processing of the print job, and the process is returned to Step S 3 after the value to which “1” has been added is set to “N”. Accordingly, the print job the present position of which is acquired is shifted in the order of priority as follows: the print job having the first priority ⁇ the print job having the second priority ⁇ the print job having the third priority . . . .
- the replacement processing unit 25 replaces the priorities of the print jobs using the flowchart in FIG. 9 according to a result of replacement determination described later (Step S 10 ).
- the standby processing unit 26 counts the time being kept by the timer 15 illustrated in FIG. 1 corresponding to the time allocated as the interval (Int) between pieces of update processing of the print job to cause the update processing to be in a standby state.
- the update processing returns to Step S 1 , and the check unit 21 checks the number of the print jobs stored in the job DB 29 again.
- the flowchart in FIG. 9 illustrates a procedure of replacement determination processing of the priorities for determining whether to perform replacement processing of the priorities.
- the check unit 21 checks the number of the print jobs stored in the job DB 29 . If the number of the print jobs stored in the job DB 29 is equal to or smaller than 1 (No at Step S 21 ), the replacement processing of the priorities of the print jobs is not required, so that the process of the flowchart in FIG. 9 is ended as it is. On the other hand, when the number of the print jobs stored in the job DB 29 is equal to or larger than 2 (Yes at Step S 21 ), the process proceeds to Step S 22 .
- the replacement processing unit 25 sets, to be “1”, the number for designating the print job on which priority replacement determination is performed (1 ⁇ N).
- the replacement processing unit 25 performs replacement determination sequentially from the print job having the first priority. Due to this, in performing update processing for the first time, the information of “N ⁇ 1” is stored in the RAM 18 or the like to designate replacement determination processing of the print job having the first priority.
- the replacement processing unit 25 compares the collection times of the adjacent print jobs with each other, and determines whether the collection time for the print job having a lower priority is shorter. For example, the collection time TN for the printed matter corresponding to the print job having the first priority is compared with the collection time TN+1 for the printed matter corresponding to the print job having the second priority. In this case, at Step S 23 , the replacement processing unit 25 determines whether the collection time (TN+1) for the printed matter corresponding to the print job having the second priority is shorter than the collection time (TN) for the printed matter corresponding to the print job having the first priority (TN>TN+1).
- Step S 26 the check unit 21 determines whether another print job on which the replacement determination is not performed is stored in the job DB 29 . If it is determined that the other print job on which the replacement determination is not performed is not stored (No at Step S 26 ), the process of the flowchart in FIG. 9 is ended as it is.
- Step S 26 the process proceeds to Step S 27 .
- the replacement processing unit 25 increments the number for designating the print job by one to designate the print job on which the replacement determination is subsequently performed (N ⁇ N+1). Due to this, at Step S 23 , for example, the collection time for the print job having the second priority is compared with the collection time for the print job having the third priority, and it is determined whether the collection time for the print job having a lower priority is shorter.
- Step S 23 if it is determined that the collection time for the print job having a lower priority is shorter (Yes at Step S 23 ), the process proceeds to Step S 24 .
- Step S 24 it is determined whether the execution of the print job having a higher priority is inconveniently caused to be in a standby state when the replacement processing unit 25 has replaced the priorities of the print jobs. In this determination, the collection time for the print job having a higher priority is assumed to be “TN”, the printing processing time for the printing job having the N-th priority is assumed to be “CN”, and the printing processing time for the print job having the (N+1)-th priority subsequent to the N-th priority is assumed to be “CN+1”.
- the replacement processing unit 25 determines that the execution of the print job having a higher priority is not caused to be in a standby state by replacing the priorities of the print jobs (Yes at Step S 24 ) if having determined that a condition of “TN ⁇ CN ⁇ CN+1 ⁇ 0” is satisfied.
- the replacement processing unit 25 advances the process to Step S 25 , and performs replacement processing of the priorities of the print jobs between the print job having a higher priority and the print job having the priority subsequent to the print job having a higher priority (refer to FIG. 5 ).
- the replacement processing unit 25 makes a determination of “No” at Step S 24 , and advances the process to Step S 26 without replacing the priorities.
- Step S 26 the check unit 21 determines whether another print job on which the replacement determination is not performed is stored in the job DB 29 . If it is determined that the other print job on which the replacement determination is not performed is not stored therein (No at Step S 26 ), the process of the flowchart in FIG. 9 is ended as it is. On the other hand, if it is determined that the other print job on which the replacement determination is not performed is stored therein (Yes at Step S 26 ), the process proceeds to Step S 27 .
- Step S 27 the replacement processing unit 25 increments, by one, the number N for designating the print job on which the priority replacement determination is subsequently performed (N ⁇ N+1), and returns the process to Step S 23 . Accordingly, the replacement determination is repeatedly performed.
- the MFP 1 sequentially adds the priorities to the print jobs transmitted via the portable terminal device 2 or input via the operation unit 13 .
- the MFP 1 periodically acquires (monitors) the present position of the portable terminal device 2 (or the personal computer device 3 ) that has transmitted the print job.
- the MFP 1 uses the present position of the portable terminal device 2 , the moving speed of the portable terminal device 2 , the distance between the portable terminal device 2 and the MFP 1 , the time required for executing the print job, and/or the like to determine whether the user that has transmitted the print job having a higher priority can immediately collect the printed matter when he/she arrives even when the print job having a lower priority is executed in a time period until the user that has transmitted the print job having a higher priority comes to collect the printed matter. If it is determined that the user that has transmitted the print job having a higher priority can immediately collect the printed matter when he/she arrives even when the print job having a lower priority is executed, the MFP 1 replaces the priorities of the print jobs.
- the print job of the user at a position near the MFP 1 can be completed in a time period until the user at a distant place comes to collect the printed matter
- the print job of the user at the near place can be processed in preference to the print job of the user at the distant place. Due to this, the time until the user at a place distant from the MFP 1 comes to collect the printed matter can be effectively utilized, the user near the MFP 1 can be prevented from wastefully waiting, and efficient processing of the print job can be achieved.
- the MFP 1 periodically acquires the positional information and updates the priorities. Due to this, when the user B having a lower priority comes closer to the MFP 1 than the user A having a higher priority who is moving toward the MFP 1 , the priority of the user B can be changed to be higher than the priority of the user A, and finer control can be achieved. Moreover, in this case, such finer control can be achieved even when an inexpensive GPS that detects the positional information in a two-dimensional range is used as the GPS 33 of the portable terminal device 2 .
- the MFP 1 is arranged on the first floor of a house, the user A is positioned on the fiftieth floor of the same house, and the user B is positioned on the third floor of the same house.
- the user B positioned on the third floor is closer to the MFP 1 placed on the first floor than the user A positioned on the fiftieth floor.
- the GPS that has difficulty in detecting the positional information other than within the two-dimensional range, the distance between the user A and the MFP 1 and the distance between the user B and the MFP 1 are detected to be substantially the same.
- the positional information is periodically acquired as in the information processing system according to the embodiment, it can be detected that the user A is closer to the MFP 1 than the user B at the time when the user A goes down to the first floor from the fiftieth floor using an elevator and starts to walk toward the MFP 1 , for example, and the priorities can be replaced with each other.
- the portable terminal device 2 that has transmitted the print job periodically detects the positional information of itself and transmits it to the MFP 1 .
- the portable terminal device 2 may be configured to transmit the positional information of itself when having received a transmission request of the positional information from the MFP 1 . Also in this case, the same effect as described above can be obtained.
- the MFP 1 directly communicates with the portable terminal device 2 .
- the MFP 1 communicates with the portable terminal device 2 via a server device.
- FIG. 10 is a system configuration diagram of the information processing system according to the second embodiment.
- a server device 50 is provided on the network 4 .

- FIG. 11 is a hardware configuration diagram of the server device 50 .
- the server device 50 has a configuration similar to that of a typical personal computer device.
- the server device 50 includes a communication unit 51 , a ROM 52 , a RAM 53 , a CPU 54 , and an HDD 55 . From the communication unit 51 to the HDD 55 are connected to each other via a bus line 56 .
- the HDD 55 stores a printing processing program for the server device 50 .
- the CPU 54 operates according to the printing processing program stored in the HDD 55 to mediate the communication between the MFP 1 and the portable terminal device 2 .
- the CPU 54 of the server device 50 receives the print job transmitted from the portable terminal device 2 , and transmits the print job to the MFP 1 .
- the CPU 54 of the server device 50 also receives the positional information that is periodically detected and transmitted by the portable terminal device 2 that has transmitted the print job, and transmits the positional information to the MFP 1 .
- the CPU 54 of the server device 50 transmits the request for acquiring the present position from the MFP 1 to the portable terminal device 2 .
- the CPU 54 of the server device 50 transmits the positional information transmitted from the portable terminal device 2 in response to the request for acquiring the present position to the MFP 1 .
- the following describes a first modification of the information processing system according to each of the embodiments described above.
- all the print jobs stored in the job DB 29 are caused to be determination targets of priority replacement processing.
- the print job in which the distance L between the MFP 1 and the portable terminal device 2 of the sender of the print job is equal to or larger than a certain distance is caused to be the determination target of the priority replacement processing to perform priority replacement processing. Due to this, the number of operations for the priority replacement processing can be reduced, and a burden on the replacement processing unit 25 can be reduced.
- the replacement processing unit 25 calculates the distance L between the MFP 1 and the portable terminal device 2 of the sender of each print job.
- the sender of the print job is positioned near the MFP 1 .
- the printed matter corresponding to the print job is highly likely to be collected by the sender in a short time. Due to this, the replacement processing unit 25 performs the priority replacement processing using, as the determination target of the priority replacement processing, the print job of the portable terminal device 2 the distance L of which from the MFP 1 is equal to or larger than a certain distance.
- the replacement processing unit 25 excludes, from the determination target of the priority replacement processing, the print job of the portable terminal device 2 the distance L of which from the MFP 1 is equal to or smaller than a certain distance. The replacement processing unit 25 then performs the replacement processing described above on the other print jobs remained after the exclusion.
- the following describes a second modification of the information processing system according to each of the embodiments described above.
- the priority replacement processing is performed in units of print jobs.
- the priority replacement processing is performed on the print job in units of pages.
- the replacement determination of a priority described with reference to FIG. 7 is performed on the print job currently being executed and the print job having the highest priority in the print job queue (the print job having the first priority). If it is determined that the print job being executed should be replaced with the print job having the first priority in the replacement determination (if it is determined that the print job having the first priority should be executed rather than the print job being executed), the replacement processing unit 25 temporarily stops the print job being executed, and stores the print job in a print job interruption stack provided in the RAM 18 . The CPU 16 then controls execution of the print job having the first priority instead.
- the CPU 16 restarts the print job in the midst of execution that has been stored in the print job interruption stack.
- the print job being executed is temporarily stopped and the other print job is executed, that is, the printing process can be performed while replacing the priorities of the print jobs in units of pages.
- the CPU 16 uses the positional information representing the present position of the portable terminal device 2 to determine the distance between the user of the interruption printing and the MFP 1 .
- the CPU 16 determines that the printed matter of the interruption printing is collected by the user of the interruption printing and restarts the print job that has been temporarily stopped.
- the printed matter of the print job that has been temporarily stopped is prevented from being mixed with the printed matter of the interruption printing.
- FIG. 12 is a flowchart illustrating a procedure of processing for determining whether to replace the print job being executed with the print job having the first priority that is stored in the print job queue.
- the flowchart in FIG. 12 is started when the print job is started to be executed, and the process starts from Step S 31 .
- the collection time calculation unit 24 calculates the collection time for the printed matter corresponding to the print job having the first priority (the print job having the highest priority) and the collection time for the printed matter of the print job currently being executed.
- the replacement processing unit 25 determines whether the collection time for the printed matter corresponding to the print job having the first priority is shorter than the collection time for the printed matter of the print job currently being executed. That is, at Step S 32 , the replacement processing unit 25 determines whether the printed matter corresponding to the print job having the first priority will be collected before the print job currently being executed is completed. If the print job currently being executed will be completed before the printed matter corresponding to the print job having the first priority is collected (No at Step S 32 ), the CPU 16 ends the process of the flowchart in FIG. 12 as it is. On the other hand, if the printed matter corresponding to the print job having the first priority is estimated to be collected before the print job currently being executed is completed (Yes at Step S 32 ), the process proceeds to Step S 33 .
- Step S 33 the replacement processing unit 25 determines whether the user who comes to collect the printed matter of the print job currently being executed can immediately collect the printed matter even when the print job currently being executed is temporarily stopped and interrupted by the print job having the first priority to be executed. If it is determined that the user will be made to wait (No at Step S 33 ), the CPU 16 ends the process of the flowchart in FIG. 12 as it is. On the other hand, if it is determined that the user will not be made to wait (Yes at Step S 33 ), the process proceeds to Step S 34 .
- Step S 34 the replacement processing unit 25 temporarily stops the print job currently being executed, and executes the interrupting print job having the first priority.
- FIG. 13 schematically illustrates such interruption printing.
- the print job represented by a circle of a dotted line is the print job currently being executed.
- the replacement processing unit 25 temporarily stops the print job currently being executed, and stores the print job in a print job interruption stack 61 that is arranged in a storage unit such as the RAM 18 and stores the print job in a Last In First Out (LIFO) format.
- the replacement processing unit 25 acquires a first print job having the first priority from the print job interruption stack 61 in place of the stored print job. Accordingly, the execution of the print job currently being executed is temporarily stopped, and the first print job becomes the print job to be executed.
- LIFO Last In First Out
- the CPU 16 executes the replaced first print job. After the first print job is completed, the print job temporarily stopped that has been stored in the print job interruption stack 61 is read out and restarted. Thus, the printing processing can be performed while replacing the priorities of the print jobs in units of pages, and print waiting time for the first print job can be further reduced.
- FIG. 14 is a flowchart illustrating a procedure for restarting the print job that has been temporarily stopped after the interruption printing is completed.
- the flowchart in FIG. 14 is started when the interruption printing is completed, and the process starts from Step S 41 .
- the CPU 16 determines whether the print job being executed is present. That is, at Step S 41 , the CPU 16 determines whether the print job of the interruption printing is being executed. If the print job of the interruption printing is being executed (Yes at Step S 41 ), the flowchart in FIG. 14 is ended as it is. On the other hand, if the print job of the interruption printing is completed (No at Step S 41 ), the process proceeds to Step S 42 .
- Step S 42 the CPU 16 determines the number of print job queues stored in the print job interruption stack 61 .
- the print job that has been temporarily stopped is stored in the print job interruption stack 61 .
- the CPU 16 advances the process to Step S 43 .
- the CPU 16 ends the process of the flowchart in FIG. 12 as it is.
- Step S 43 the CPU 16 determines whether there is a paper ejection tray (empty tray) onto which the ejected printed matter is currently not present, the paper ejection tray being different from the paper ejection tray onto which the printed matter of the interruption printing has been ejected. That is, in this example, the MFP 1 includes a plurality of paper ejection trays. In a case of an MFP including only one paper ejection tray, the process at Step S 43 is skipped. If the empty tray is present (Yes at Step S 43 ), the process proceeds to Step S 46 .
- Step S 46 the CPU 16 acquires the print job temporarily stopped that has been stored in the print job interruption stack 61 and restarts the print job.
- the CPU 16 controls a paper ejection mechanism so that the printed matter of the restarted print job will be ejected onto the empty tray detected at Step S 43 . Due to this, the printed matter of the interruption printing can be prevented from being mixed with the printed matter of the print job the execution of which has been temporarily stopped, on the same paper ejection tray.
- the CPU 16 may control the paper ejection mechanism to detect the paper ejection tray used when the execution of the print job was temporarily stopped as the empty tray described above, and cause the printed matter of the restarted print job to be ejected thereon.
- Step S 43 the CPU 16 advances the process to Step S 44 .
- Step S 44 the CPU 16 determines whether a time-out function of waiting for collection of the printed matter is set to be ON.
- the information processing system has the time-out function of waiting for collection of the printed matter to wait for restart of the print job that has been temporarily stopped until the collection time at which the printed matter of the interruption printing is collected by the user.
- the time-out function can be set by an administrator of the MFP 1 via a setting menu. By way of example, the time-out function is set to be ON in a default setting.
- the setting information of the time-out function is stored in the storage unit such as the RAM 18 , the HDD 19 , and the ROM 17 illustrated in FIG. 1 .
- the CPU 16 refers to the setting information stored in the storage unit to determine whether the time-out function is set to be ON.
- Step S 44 If the time-out function is set to be ON (Yes at Step S 44 ), the process proceeds to Step S 47 , and the CPU 16 waits for restart of the print job that has been temporarily stopped until the collection time calculated by the collection time calculation unit 24 at which the printed matter of the interruption printing will be collected by the user. When the collection time has been reached, the CPU 16 determines that the printed matter of the interruption printing is collected by the user, and restarts, at Step S 46 , the print job that has been temporarily stopped.
- the CPU 16 determines whether the distance between the MFP 1 and the present position of the portable terminal device 2 of the user of the interruption printing acquired by the position acquisition unit 22 becomes the distance at which the printed matter of the interruption printing can be collected. That is, when the distance between the user of the interruption printing and the MFP 1 is, for example, equal to or smaller than 30 cm, it can be said that the user can collect the printed matter of the interruption printing from the paper ejection tray of the MFP 1 at that distance.
- the CPU 16 determines that the printed matter has been collected when the distance between the user of the interruption printing and the MFP 1 has become equal to or smaller than the distance at which the user can collect the printed matter of the interruption printing (Yes at Step S 45 ), and restarts the print job that has been temporarily stopped at Step S 46 .
- the information processing system temporarily stops the print job being executed when having detected the print job in which the collection time for the printed matter is estimated to be earlier than the collection time for the printed matter of the print job being executed. Then interruption printing of the print job in which the collection time for the printed matter is estimated to be earlier is performed, and the print job that has been temporarily stopped is restarted after the interruption printing is completed. Accordingly, the printing processing can be performed while replacing the priorities of the print jobs in units of pages, the print waiting time for the user can be further reduced, and the same effect as the embodiments described above can be obtained.
- the information processing system waits for restart of the print job that has been temporarily stopped until the collection time at which the printed matter of the interruption printing will be collected by the user.
- the information processing system determines that the printed matter of the interruption printing has been collected by the user, and restarts the print job that has been temporarily stopped. Accordingly, the print job that has been temporarily stopped can be restarted after the printed matter of the interruption printing has been collected by the user, and the printed matter of the interruption printing can be prevented from being mixed with the printed matter of the print job that has been temporarily stopped. That is, the user can collect the printed matter of the preceding print job and the printed matter of the interruption printing clearly separately from each other.
- the information processing system determines that the printed matter of the interruption printing is collected by the user, and restarts the print job that has been temporarily stopped. Accordingly, the print job that has been temporarily stopped can be restarted after the printed matter of the interruption printing is collected by the user, and the printed matter of the interruption printing can be prevented from being mixed with the printed matter of the print job that has been temporarily stopped. That is, the user can collect the printed matter of the preceding print job and the printed matter of the interruption printing clearly separately from each other.
- the printed matter of the restarted print job is ejected onto the empty tray. Accordingly, the printed matter of the interruption printing can be prevented from being mixed with the printed matter of the print job that has been temporarily stopped, and the user can collect the printed matter of the preceding print job and the printed matter of the interruption printing clearly separately from each other.
- the information processing system may continuously perform the replacement determination during execution of the print job, may perform priority replacement processing by interrupting the print job being executed if the condition described with reference to FIG. 7 is satisfied, and may process the print job according to the replaced priorities (interruption).
- each print job is processed as interruption such that the print job having a lower priority is executed during printing of the print job having a higher priority, for example. Accordingly, the print job can be executed while performing finer replacement processing.
- efficiency of information output can be enhanced.

- Japanese Laid-open Patent Publication No. 2003-167703 discloses a job processing method performed by a printer for setting a priority order of execution appropriate for each print job to be processed when a plurality of print jobs are transmitted to one MFP. In this job processing method, printing operation time and the number of sheets to be printed are calculated for each print job. As a result of calculation, a priority is given to each print job. Accordingly, when the print jobs compete with each other in a printer device, an optimum order of priority can be determined to execute printing.
- However, MFPs in the related art that can be remotely controlled via a portable terminal device process a print job transmitted from the portable terminal device in the same way as a print job received via an operation panel installed in the MFP. For example, when a print job transmitted from the portable terminal device of a user at a place distant from the MFP has been received earlier than a print job of a user at a position near the MFP, the MFP processes the print job of the user at the distant position in preference to the print job of the user at the position near the MFP.
- Due to this, the user at the position near the MFP needs to wastefully wait until the print job of the user at the distant position, who takes time to collect printed matter, is finished although the user near the MFP can immediately collect the printed matter.
- In the job processing method performed by the printer disclosed in Japanese Laid-open Patent Publication No. 2003-167703, the priority of each print job is determined from a calculation result of the number of sheets to be printed and the printing operation time for each print job. Accordingly, similarly to the above case, there is a problem that the print job of the user at the distant place, who takes time to collect the printed matter, is executed earlier, and the user at the position near the MFP needs to wastefully wait for processing of the print job although he/she can immediately collect the printed matter.
- In view of such a problem as described above, the job processing methods in the MFP in the related art that can be remotely controlled via the portable terminal device and the printer disclosed in Japanese Laid-open Patent Publication No. 2003-167703 have been inefficient printing methods.
- In view of the above, there is a need to provide an information processing device, an information processing system, and an information processing method that can enhance efficiency of information output.
- It is an object of the present invention to at least partially solve the problems in the conventional technology.
- An information processing device includes: a storage processing unit that receives an information processing request transmitted from a terminal device and then stores the information processing request and a priority for executing the information processing request in a storage unit in association with each other; an information processing unit that executes information processing requests stored in the storage unit in order from an information processing request in association with which a higher priority is stored; a moving speed calculation unit that calculates a moving speed of the terminal device based on, out of positional information transmitted at predetermined timings from the terminal device that has transmitted the information processing request, first positional information transmitted at a first timing and second positional information transmitted at a second timing subsequent to the first positional information; a time calculation unit that calculates a time until a distance between the terminal device and the information processing device becomes equal to or smaller than a predetermined value based on the moving speed calculated by the moving speed calculation unit, positional information of the information processing device, and the second positional information; and a replacement processing unit that replaces, when a second time as a time until the distance between a second terminal device that has transmitted a second information processing request having a lower priority and the information processing device becomes equal to or smaller than a predetermined value is shorter than a first time as a time until the distance between a first terminal device that has transmitted a first information processing request having a higher priority and the information processing device becomes equal to or smaller than a predetermined value, the priorities stored in the storage unit in association with the first information processing request and the second information processing request such that the second information processing request having the lower priority is processed earlier than the first information processing request having the higher priority.
- An information processing system includes: a terminal device; an information processing device; and a server device. The terminal device detects and transmits a current position at predetermined timings after transmitting an information processing request. The information processing device includes: a storage processing unit that receives the information processing request transmitted from the terminal device and then stores the information processing request and a priority for executing the information processing request in a storage unit in association with each other; an information processing unit that executes information processing requests stored in the storage unit in order from an information processing request in association with which a higher priority is stored; a moving speed calculation unit that calculates a moving speed of the terminal device based on, out of positional information transmitted at the predetermined timings from the terminal device that has transmitted the information processing request, first positional information transmitted at a first timing and second positional information transmitted at a second timing subsequent to the first positional information; a time calculation unit that calculates a time until a distance between the terminal device and the information processing device becomes equal to or smaller than a predetermined value based on the moving speed calculated by the moving speed calculation unit, positional information of the information processing device, and the second positional information; and a replacement processing unit that replaces, when a second time as a time until the distance between a second terminal device that has transmitted a second information processing request having a lower priority and the information processing device becomes equal to or smaller than a predetermined value is shorter than a first time as a time until the distance between a first terminal device that has transmitted a first information processing request having a higher priority and the information processing device becomes equal to or smaller than a predetermined value, the priorities stored in the storage unit in association with the first information processing request and the second information processing request such that the second information processing request having the lower priority is processed earlier than the first information processing request having the higher priority. The server device receives the information processing request and the detected current position from the terminal device and transmits the information processing request and the detected current position to the information processing device.
- An information processing method is performed by an information processing device. The method includes: by a storage processing unit, receiving an information processing request transmitted from a terminal device and then storing the information processing request and a priority for executing the information processing request in a storage unit in association with each other; by an information processing unit, executing information processing requests stored in the storage unit in order from an information processing request in association with which a higher priority is stored; by a moving speed calculation unit, calculating a moving speed of the terminal device based on, out of positional information transmitted at predetermined timings from the terminal device that has transmitted the information processing request, first positional information transmitted at a first timing and second positional information transmitted at a second timing subsequent to the first positional information; by a time calculation unit, calculating a time until a distance between the terminal device and the information processing device becomes equal to or smaller than a predetermined value based on the moving speed calculated by the moving speed calculation unit, positional information of the information processing device, and the second positional information; and by a replacement processing unit, when a second time as a time until the distance between a second terminal device that has transmitted a second information processing request having a lower priority and the information processing device becomes equal to or smaller than a predetermined value is shorter than a first time as a time until the distance between a first terminal device that has transmitted a first information processing request having a higher priority and the information processing device becomes equal to or smaller than a predetermined value, replacing the priorities stored in the storage unit in association with the first information processing request and the second information processing request such that the second information processing request having the lower priority is processed earlier than the first information processing request having the higher priority.

- Outline
- In the information processing system according to an embodiment, a multifunction peripheral (MFP) that can be remotely controlled by a portable terminal device acquires, at predetermined timings (for example, periodically), positional information of a portable terminal device that has transmitted a print job. The MFP detects a moving speed from the positional information of a user. If the print job of a user positioned near the MFP can be completed by the time when a user at a distant place comes to collect printed matter, the MFP processes the print job of the user at the near place in preference to the print job of the user at the distant place.
- Due to this, the print job of the user near the MFP can be executed by the time when the user at a place distant from the MFP comes to collect the printed matter. Accordingly, the time until the user at the place distant from the MFP comes to collect the printed matter can be effectively utilized, the user near the MFP can be prevented from wastefully waiting, and efficient processing of the print job can be achieved.

FIG. 1 is a system configuration diagram of an information processing system according to a first embodiment. The information processing system according to the first embodiment includes anMFP 1 and terminal devices. The terminal devices include a portableterminal device 2 and apersonal computer device 3. The portableterminal device 2 is an example of the terminal device, and communicates with theMFP 1 through ad hoc communication. Alternatively, the portableterminal device 2 communicates with theMFP 1 via apredetermined network 4 such as the Internet through infrastructure communication. - The
MFP 1 includes acommunication unit 11, an engine unit 12, anoperation unit 13, a GPS 14, atimer 15, aCPU 16, a ROM 17, aRAM 18, and anHDD 19. Thecommunication unit 11 has both of a wireless communication function and a wired communication function, and performs the ad hoc communication or the infrastructure communication described above between itself and the portableterminal device 2 and thepersonal computer device 3. The engine unit 12 as an example of an information processing unit has various functions related to image formation and/or the like such as a printing function, a scanner function, a facsimile function, and a copying function, and executes a function designated by a user or the like. The engine unit 12 causes a character, an image, and/or the like to be printed on a physical medium such as a paper medium. The engine unit 12 may cause information to be output to a storage medium such as a semiconductor memory. - The
operation unit 13 is what is called a touch panel. On theoperation unit 13, displayed is an icon for selecting a desired function, an icon for instructing a desired setting, and/or the like. The user performs touch operation on a desired icon. TheMFP 1 performs information processing corresponding to the icon displayed at a touch operation position. GPS is an abbreviation for a “global positioning system”. The GPS 14 detects a present position of theMFP 1. MFP positional information representing the detected present position of theMFP 1 is used by theCPU 16 to calculate a moving distance of the portableterminal device 2, for example. Alternatively, the GPS 14 detects the present position of theMFP 1 in advance. The detected present position is stored in theHDD 19 as the MFP positional information. The MFP positional information may be manually input, for example. TheCPU 16 reads out the MFP positional information stored in theHDD 19 and uses it for calculating the moving distance of the portableterminal device 2, for example. The GPS 14 is an example of a position acquisition unit. TheCPU 16 is an example of a storage processing unit. TheHDD 19 is an example of a storage unit. - The
timer 15 counts a time corresponding to an interval for performing replacement processing of priorities of print jobs. As described later as an example, theMFP 1 periodically acquires the present position of the portableterminal device 2 or the like, calculates a distance therefrom, and replaces priorities of print jobs with each other. Thetimer 15 counts the time corresponding to the interval for performing such replacement processing. - CPU is an abbreviation for a “central processing unit”. The
CPU 16 controls the entire operation of theMFP 1 in addition to replacement control of the priorities of the print jobs described later. ROM is an abbreviation for a “read only memory”. The ROM 17 stores a predetermined computer program such as an operation system for performing basic operation control on theCPU 16. RAM is an abbreviation for a “random access memory”. TheRAM 18 stores a job database (job DB) 29. TheRAM 18 may be used as an example of the storage unit. Thejob DB 29 stores the print jobs to which the priorities (described later) are given. Thejob DB 29 may be stored in another storage unit such as the ROM 17 and theHDD 19. HDD is an abbreviation for a “hard disk drive”. TheHDD 19 stores aprinting processing program 19 that processes the print job while replacing the priorities of the print jobs depending on the distance between theMFP 1 and the portableterminal device 2 or the like. TheHDD 19 stores the MFP positional information described above. The printing processing program and the MFP positional information may be stored in another storage unit such as the ROM 17 and theRAM 18. - The printing processing program may be recorded and provided in a computer-readable recording medium such as a compact disc read only memory (CD-ROM) and a flexible disk (FD) as an installable or executable file. Alternatively, the printing processing program may be recorded and provided in a computer-readable recording medium such as a compact disc recordable (CD-R), a digital versatile disc (DVD), a Blu-ray Disc (registered trademark), and a semiconductor memory. DVD is an abbreviation for a “digital versatile disc”. The printing processing program may be provided to be installed via a network such as the Internet. The printing processing program may be embedded in advance and provided in a ROM or the like in a device.

FIG. 2 is a functional block diagram of each function implemented when theCPU 16 operates according to the printing processing program. As illustrated inFIG. 2 , theCPU 16 operates according to the printing processing program to implement, as software, respective functions of acheck unit 21, aposition acquisition unit 22, a movingspeed calculation unit 23, a collectiontime calculation unit 24, areplacement processing unit 25, and astandby processing unit 26. In this example, from thecheck unit 21 to thestandby processing unit 26 are assumed to be implemented as software. However, some or all of thecheck unit 21 to thestandby processing unit 26 may be implemented as hardware. - The
check unit 21 checks the number of print jobs currently stored in thejob DB 29. Theposition acquisition unit 22 acquires the positional information of each portableterminal device 2 and thepersonal computer device 3. The movingspeed calculation unit 23 as an example of a moving speed detection unit calculates the moving speed of each portableterminal device 2. The collectiontime calculation unit 24 as an example of a time calculation unit calculates a collection time for the printed matter that is estimated from the present position and the moving speed of each portableterminal device 2. Thereplacement processing unit 25 performs processing for replacing the priorities of the print jobs stored in thejob DB 29 according to the estimated collection time and the like. Thestandby processing unit 26 controls the replacement processing to be in a standby state from when the replacement processing of priorities is performed until the next replacement processing is performed. -
FIG. 3 is a hardware configuration diagram of the portableterminal device 2. The portableterminal device 2 includes a communication unit 31, anoperation unit 32, a GPS 33, a CPU 34, aROM 35, aRAM 36, and anHDD 37. From the communication unit 31 to theHDD 37 are connected to each other via abus line 30. The communication unit 31 performs ad hoc communication or infrastructure communication between itself and theMFP 1. Theoperation unit 32 is what is called a touch panel. On theoperation unit 32, displayed is an icon or the like for performing a desired operation such as a print setting and a print instruction for the printed matter. The user performs touch operation on a desired icon. The CPU 34 transmits a command such as a print instruction corresponding to the touch-operated icon to theMFP 1 using the ad hoc communication or the infrastructure communication. - The
GPS 23 detects the present position of the portableterminal device 2 periodically or when having received a transmission request from theMFP 1. The CPU 34 transmits the detected present position to theMFP 1 via the communication unit 31. In this case, every time when theGPS 23 detects the present position, the CPU 34 compares the detected present position with the position detected in the last time. Only when a difference between the former and latter positions is equal to or larger than a predetermined difference (equal to or larger than a predetermined moving distance), the CPU 34 transmits the present position to theMFP 1. This configuration can prevent the same present position from being wastefully transmitted to theMFP 1 when the present position of the portableterminal device 2 has not moved because the user is standing still. The CPU 34 also controls the entire portableterminal device 2. - The
ROM 35 stores a computer program such as an operation system of the portableterminal device 2. The CPU 34 operates according to an operation program to control an operation of the portableterminal device 2. TheHDD 37 stores a printing processing program for a portable terminal device for printing the printed matter by remotely controlling theMFP 1. When the instruction to print the printed matter is given by the user, the CPU 34 loads the printing processing program on theRAM 36 to execute it, and transmits the present position of the portableterminal device 2, for example. -
FIG. 4 is a diagram illustrating a configuration of the print job stored in thejob DB 29 in theRAM 18 of theMFP 1. As illustrated inFIG. 4 , a “distance” between theMFP 1 and the portable terminal device 2 (or the personal computer device 3) that has transmitted the print job is calculated and added to each print job in addition to basic printing information such as the number of sheets to be printed and print colors. A “printing time” estimated from the number of print copies and the printing speed of the print job is also calculated and added thereto. Also added thereto is a “collection time” that is a time until the user comes to collect the printed matter and estimated from the positional information of the portableterminal device 2 or the like acquired in the last time and the positional information of the portableterminal device 2 or the like acquired in this time. Additionally, also added thereto is a “priority” that is given corresponding to the “distance”, the “collection time”, the “printing time”, and/or the like. - The example of
FIG. 4 illustrates a case in which, regarding a print job A, the distance between the portableterminal device 2 and theMFP 1 is Pa (m), the estimated collection time is Ra (min), the estimated printing time is Ca (min), and the first priority is given thereto. Similarly, regarding a print job B, the distance between the portableterminal device 2 and theMFP 1 is Pb (m), the estimated collection time is Rb (min), the estimated printing time is Cb (min), and the second priority is given thereto. A “receiving time” of each print job may be added to each print job together with the “distance”, the “collection time”, the “printing time”, and the “priority”. -
FIG. 5 is a diagram schematically illustrating a storage form of the print job stored in the job DB 29 (print job queue) in theRAM 18. TheCPU 16 receives the print job transmitted from the portableterminal device 2, and receives the print job input via theoperation unit 13. TheCPU 16 operates as an example of a storage processing unit to add the priorities to the print jobs in a received order as illustrated inFIG. 5 , and controls the print jobs to be stored in thejob DB 29. TheCPU 16 checks thejob DB 29 after the print job being currently executed is completed. If there is any print job stored therein, theCPU 16 processes the print job in the order of priority. - The
CPU 16 revises the priority according to the “distance”, the “collection time”, the “printing time”, and/or the like described above. When the replacement processing of priorities is required, theCPU 16 performs replacement processing for causing the print job to which a lower priority is given to have a higher priority. The example ofFIG. 5 illustrates a case in which a third print job having the third priority is replaced with a fourth print job having the fourth priority. - Next,
FIGS. 6A and 6B are diagrams for explaining information used by theMFP 1 for replacing the priorities of printing. TheMFP 1 periodically acquires the present position of the portableterminal device 2 or the like that has transmitted the print job using the ad hoc communication or the infrastructure communication as described above. At a certain time H1, theMFP 1 calculates the distance between the portableterminal device 2 and theMFP 1 based on the present position of the portableterminal device 2 or the like and the present position of theMFP 1. TheMFP 1 handles the calculated distance as a distance L to a sender (portable terminal device 2) of the print job. - The
MFP 1 periodically calculates the distance L to the sender (portable terminal device 2). A difference between a distance L1 to the sender that is first calculated at the time H1 and a distance L2 to the sender that is calculated next at a time H2 is a moving distance M of the sender (M=L2−L1). A value obtained by dividing the moving distance M by a time (H2−H1) between when the present positions of the portableterminal device 2 have been acquired is a moving speed V of the sender. A value obtained by dividing the distance L by the moving speed V is an estimated time T until the sender comes to collect the printed matter. - The
MFP 1 updates such pieces of information every time when acquiring the present position of the portableterminal device 2, and adds the pieces of information to the corresponding print job to store them in thejob DB 29. TheMFP 1 performs replacement determination of priorities of the print jobs using these pieces of information, the N-th priority of the print job, and a processing time C of the print job. TheMFP 1 performs replacement processing of the priorities of the print jobs according to a result of the replacement determination. -
FIG. 7 is a diagram for explaining the replacement determination of the priorities of the print jobs. TheMFP 1 processes the print jobs in the received order in principle. That is, theMFP 1 preferentially processes the print job that has been transmitted earlier. However, when it is estimated that the user that has transmitted the print job later will come to collect the printed matter earlier than the user that has transmitted the print job earlier (the former user will come to collect the printed matter in a short time), theMFP 1 performs processing of replacing the priorities of both print jobs. Due to this, the printed matter of the user that has transmitted the print job later can be printed in a time period until the user that has transmitted the print job earlier comes to collect the printed matter, so that efficient printing processing can be performed. - In this case, the printed matter of the user that has transmitted the print job later may be printed in a time period until the user that has transmitted the print job earlier comes to collect the printed matter. However, when a total time required for printing the earlier print job and the later print job is longer than the time until the user that has transmitted the print job earlier comes to collect the printed matter, the user that has transmitted the print job earlier inconveniently reaches the
MFP 1 before printing corresponding to the earlier print job is completed. In this case, the user that has transmitted the print job earlier needs to wait in front of theMFP 1 until the printing corresponding to the print job of himself/herself is completed. Due to this, if the replacement processing of the priorities causes the user that has transmitted the print job earlier to wait, or causes a waiting time to be longer, theMFP 1 does not perform replacement processing of the priorities as described below. Accordingly, intelligent replacement processing is performed. - A specific description will be provided below. A print collection time for a sender A of the print job is assumed to be “Ta”, and the print collection time for a sender B of the print job is assumed to be “Tb”. The priority of the sender A is assumed to be “Na”, and the priority of the sender B is assumed to be “Nb”. A printing processing time for the print job of the sender A is assumed to be “Ca”, and the printing processing time for the print job of the sender B is assumed to be “Cb”.
- For example, when a first condition of “the print collection time Ta for the sender A>the print collection time Tb for the sender B” is established as illustrated in
FIG. 7 as a first situation, it is estimated that the sender B will collect the printed matter earlier than the sender A. When a second condition of “the priority Na of the sender A>the priority Nb of the sender B” is established, the priority of the sender A is higher than the priority of the sender B. When a time obtained by subtracting the printing processing time “Ca” for the print job of the sender A and the printing processing time “Cb” for the print job of the sender B from the print collection time “Ta” of the sender A is equal to or larger than 0 (Ta−Cb−Ca≧0), the following can be said. That is, in this case, the sender A having a higher priority does not need to wait even if the print job A and the print job B are processed. In the first situation under the first to third conditions, theMFP 1 performs processing of replacing the print job of the sender A having a higher priority with the print job of the sender B having a lower priority. - Similarly, when the first condition of “the print collection time Ta for the sender A>the print collection time Tb for the sender B” is established as illustrated in
FIG. 7 as a second situation, it is estimated that the sender B will collect the printed matter earlier than the sender A. When the second condition of “the priority Na of the sender A>the priority Nb of the sender B” is established, the priority of the sender A is higher than the priority of the sender B. When the time obtained by subtracting the printing processing time “Ca” for the print job of the sender A and the printing processing time “Cb” for the print job of the sender B from the print collection time “Ta” of the sender A is less than 0 (Ta−Cb−Ca<0), the following can be said. That is, in this case, the sender A having a higher priority needs to wait when the print job A and the print job B are processed. In the second situation under the first to third conditions, theMFP 1 does not perform processing of replacing the print job of the sender A with the print job of the sender B. - The
MFP 1 performs such replacement determination of the priorities and replacement processing of the priorities at a timing of updating the print job (timing of acquiring the present position of each portable terminal device or the like) between adjacent print jobs in the job DB 29 (print job queue). -
FIG. 8 is a flowchart illustrating a procedure of update processing of the print job stored in thejob DB 29 in theRAM 18. TheCPU 16 of theMFP 1 reads the printing processing program stored in theHDD 19 to load thecomponents 21 to 26 illustrated inFIG. 2 on theRAM 18 and causes the components to function. - First, at Step S1, the
check unit 21 illustrated inFIG. 2 checks the number of the print jobs stored in thejob DB 29 in theRAM 18. If the number of the print jobs stored in thejob DB 29 is “0” (the number of the print jobs >0), the process proceeds to Step S11. At Step S11, thestandby processing unit 26 counts the time being kept by thetimer 15 illustrated inFIG. 1 corresponding to the time allocated as an interval (Int) between pieces of update processing of the print job to cause the update processing to be in a standby state. When the time corresponding to the interval is counted, the update processing returns to Step S1, and thecheck unit 21 checks the number of the print jobs stored in thejob DB 29 again. - Next, when it is determined that one or more print jobs are stored in the
job DB 29 and the process proceeds to Step S2, theposition acquisition unit 22 sets a number for designating the portable terminal device 2 (or the personal computer device 3) the present position of which is acquired to be “1” (N←1). By way of example, theMFP 1 sequentially performs update processing from the print job having the first priority. Due to this, in performing update processing for the first time, information of “N←1” is stored in theRAM 18 or the like for designating the update processing of the print job having the first priority. As described later in the description of Step S12, every time when the update processing is performed on one print job, theposition acquisition unit 22 increments the number for designating the update processing of the print job one by one, as follows: N=1→N=2→N=3 . . . . Accordingly, the update processing is performed in the order of priority of each print job. - Next, at Step S3, the
position acquisition unit 22 acquires the present position of the portableterminal device 2 or the like that has transmitted the print job having the priority corresponding to the set number N. Specifically, when having received a print request from the portableterminal device 2, theMFP 1 issues unique identification information to the portableterminal device 2 together with a message that the print request has been received. - After transmitting the print job to the
MFP 1, the CPU 34 of each portableterminal device 2 illustrated inFIG. 3 detects the present position of itself via the GPS 33 every predetermined time (every interval time described above) according to the printing processing program stored in theHDD 37. The CPU 34 of the portableterminal device 2 then adds the identification information issued from theMFP 1 to the detected present position of itself, and transmits the information to theMFP 1 via the communication unit 31. Theposition acquisition unit 22 of theMFP 1 acquires, at Step S3, the present position of each portableterminal device 2 that is periodically transmitted from the portableterminal device 2 or the like. - At Step S4, the moving
speed calculation unit 23 performs an operation ofExpression 1 as follows to calculate the moving speed “MN” of the portableterminal device 2 assuming that the position of the portableterminal device 2 acquired in the last time is “PN−1”, the currently acquired present position of the same portableterminal device 2 is “PN”, and the interval for performing update processing is “Int”. -
MN=((PN−1)−PN)/Int (Expression 1) - At first, the position (PN−1) acquired in the last time is not present, so that the process at Step S4 performed by the moving
speed calculation unit 23 is skipped. - Next, at Step S5, the
position acquisition unit 22 acquires a present position PMF of theMFP 1 via the GPS 14 illustrated inFIG. 3 . At Step S6, it is determined whether theposition acquisition unit 22 has acquired the present position PMF of theMFP 1. If it is determined that the present position PMF has been acquired (Yes at Step S6), the process proceeds to Step S8. If it is determined that theposition acquisition unit 22 cannot acquire the present position PMF of the MFP 1 (No at Step S6), the process proceeds to Step S7. - At Step S7, the
position acquisition unit 22 reads out and acquires the present position of theMFP 1 that is detected by the GPS 14 in advance and stored in the storage unit such as theRAM 36 and theHDD 37 because the GPS 14 cannot acquire the present position PMF of theMFP 1. Alternatively, at Step S7, theposition acquisition unit 22 reads out and acquires the present position of theMFP 1 that is stored in the storage unit such as theRAM 36 and theHDD 37 in advance via theoperation unit 13 or the like by the user. - At Step S8, the collection
time calculation unit 24 performs an operation ofExpression 2 as follows to calculate a collection time “TN” until the user of the portableterminal device 2 comes to collect the printed matter assuming that the moving speed of the portableterminal device 2 is “MN”, the currently acquired present position of the portableterminal device 2 is “PN”, and the present position of theMFP 1 is “PMF”. The collection time “TN” is an example of a time until the distance between theMFP 1 and the portableterminal device 2 becomes equal to or smaller than a predetermined value. -
TN=(PMF−PN)/MN (Expression 2) - Next, at Step S9, the
check unit 21 determines whether the print job having the (N+1)-th priority is present in thejob DB 29. In other words, thecheck unit 21 determines whether another print job the update processing on which should be examined is stored in thejob DB 29. If it is determined that the other print job is stored (Yes at Step S9), at Step S12, thecheck unit 21 increments a current number for designating the update processing of the print job by one to shift the print job the update processing on which should be examined to the print job having the next priority. That is, “1” is added to the current number for designating the update processing of the print job, and the process is returned to Step S3 after the value to which “1” has been added is set to “N”. Accordingly, the print job the present position of which is acquired is shifted in the order of priority as follows: the print job having the first priority→the print job having the second priority→the print job having the third priority . . . . - Next, if the
check unit 21 determines that the other print job is not stored in the job DB 29 (No at Step S9), thereplacement processing unit 25 replaces the priorities of the print jobs using the flowchart inFIG. 9 according to a result of replacement determination described later (Step S10). - At Step S11, the
standby processing unit 26 counts the time being kept by thetimer 15 illustrated inFIG. 1 corresponding to the time allocated as the interval (Int) between pieces of update processing of the print job to cause the update processing to be in a standby state. When the time corresponding to the interval is counted, the update processing returns to Step S1, and thecheck unit 21 checks the number of the print jobs stored in thejob DB 29 again. - Next, the flowchart in
FIG. 9 illustrates a procedure of replacement determination processing of the priorities for determining whether to perform replacement processing of the priorities. First, at Step S21, thecheck unit 21 checks the number of the print jobs stored in thejob DB 29. If the number of the print jobs stored in thejob DB 29 is equal to or smaller than 1 (No at Step S21), the replacement processing of the priorities of the print jobs is not required, so that the process of the flowchart inFIG. 9 is ended as it is. On the other hand, when the number of the print jobs stored in thejob DB 29 is equal to or larger than 2 (Yes at Step S21), the process proceeds to Step S22. - At Step S22, the
replacement processing unit 25 sets, to be “1”, the number for designating the print job on which priority replacement determination is performed (1←N). By way of example, thereplacement processing unit 25 performs replacement determination sequentially from the print job having the first priority. Due to this, in performing update processing for the first time, the information of “N←1” is stored in theRAM 18 or the like to designate replacement determination processing of the print job having the first priority. As described later in the description of Step S27, every time when the replacement determination is performed on one print job, thereplacement processing unit 25 increments the number for designating the print job on which the replacement determination is performed one by one, as follows: N=1→N=2→N=3 . . . . Accordingly, the replacement determination is performed in the order of priority of each print job. - Next, at Step S23, as described above with reference to
FIG. 5 , thereplacement processing unit 25 compares the collection times of the adjacent print jobs with each other, and determines whether the collection time for the print job having a lower priority is shorter. For example, the collection time TN for the printed matter corresponding to the print job having the first priority is compared with the collection time TN+1 for the printed matter corresponding to the print job having the second priority. In this case, at Step S23, thereplacement processing unit 25 determines whether the collection time (TN+1) for the printed matter corresponding to the print job having the second priority is shorter than the collection time (TN) for the printed matter corresponding to the print job having the first priority (TN>TN+1). - If it is determined that the collection time for the print job having a lower priority is longer (No at Step S23), the replacement processing of the priorities is not required, so that the process proceeds to Step S26. At Step S26, the
check unit 21 determines whether another print job on which the replacement determination is not performed is stored in thejob DB 29. If it is determined that the other print job on which the replacement determination is not performed is not stored (No at Step S26), the process of the flowchart inFIG. 9 is ended as it is. - On the other hand, if it is determined that the other print job on which the replacement determination is not performed is stored (Yes at Step S26), the process proceeds to Step S27. At Step S27, the
replacement processing unit 25 increments the number for designating the print job by one to designate the print job on which the replacement determination is subsequently performed (N←N+1). Due to this, at Step S23, for example, the collection time for the print job having the second priority is compared with the collection time for the print job having the third priority, and it is determined whether the collection time for the print job having a lower priority is shorter. - On the other hand, at Step S23, if it is determined that the collection time for the print job having a lower priority is shorter (Yes at Step S23), the process proceeds to Step S24. At Step S24, it is determined whether the execution of the print job having a higher priority is inconveniently caused to be in a standby state when the
replacement processing unit 25 has replaced the priorities of the print jobs. In this determination, the collection time for the print job having a higher priority is assumed to be “TN”, the printing processing time for the printing job having the N-th priority is assumed to be “CN”, and the printing processing time for the print job having the (N+1)-th priority subsequent to the N-th priority is assumed to be “CN+1”. Thereplacement processing unit 25 then determines that the execution of the print job having a higher priority is not caused to be in a standby state by replacing the priorities of the print jobs (Yes at Step S24) if having determined that a condition of “TN−CN−CN+ 1≧0” is satisfied. - That is, when the collection time for the printed matter of the user corresponding to the print job having a higher priority is longer than a total time of the printing processing time for the print job having a higher priority and the printing processing time for the print job having the priority subsequent to the print job having a higher priority, the user corresponding to the print job having a higher priority can immediately collect the printed matter when he/she arrives even when the priorities are replaced with each other. Due to this, the
replacement processing unit 25 advances the process to Step S25, and performs replacement processing of the priorities of the print jobs between the print job having a higher priority and the print job having the priority subsequent to the print job having a higher priority (refer toFIG. 5 ). - On the other hand, when the condition of “TN−CN−
CN+ 1≧0” is not satisfied, the user corresponding to the print job having a higher priority will come to collect the printed matter while the print job having a higher priority and the print job having the priority subsequent to the print job having a higher priority are being executed. In this case, thereplacement processing unit 25 makes a determination of “No” at Step S24, and advances the process to Step S26 without replacing the priorities. - At Step S26, the
check unit 21 determines whether another print job on which the replacement determination is not performed is stored in thejob DB 29. If it is determined that the other print job on which the replacement determination is not performed is not stored therein (No at Step S26), the process of the flowchart inFIG. 9 is ended as it is. On the other hand, if it is determined that the other print job on which the replacement determination is not performed is stored therein (Yes at Step S26), the process proceeds to Step S27. At Step S27, thereplacement processing unit 25 increments, by one, the number N for designating the print job on which the priority replacement determination is subsequently performed (N←N+1), and returns the process to Step S23. Accordingly, the replacement determination is repeatedly performed. - As is obvious from the above description, in the information processing system according to the first embodiment, the
MFP 1 sequentially adds the priorities to the print jobs transmitted via the portableterminal device 2 or input via theoperation unit 13. TheMFP 1 periodically acquires (monitors) the present position of the portable terminal device 2 (or the personal computer device 3) that has transmitted the print job. TheMFP 1 uses the present position of the portableterminal device 2, the moving speed of the portableterminal device 2, the distance between the portableterminal device 2 and theMFP 1, the time required for executing the print job, and/or the like to determine whether the user that has transmitted the print job having a higher priority can immediately collect the printed matter when he/she arrives even when the print job having a lower priority is executed in a time period until the user that has transmitted the print job having a higher priority comes to collect the printed matter. If it is determined that the user that has transmitted the print job having a higher priority can immediately collect the printed matter when he/she arrives even when the print job having a lower priority is executed, theMFP 1 replaces the priorities of the print jobs. - Accordingly, for example, in a case in which the print job of the user at a position near the
MFP 1 can be completed in a time period until the user at a distant place comes to collect the printed matter, the print job of the user at the near place can be processed in preference to the print job of the user at the distant place. Due to this, the time until the user at a place distant from theMFP 1 comes to collect the printed matter can be effectively utilized, the user near theMFP 1 can be prevented from wastefully waiting, and efficient processing of the print job can be achieved. - The
MFP 1 periodically acquires the positional information and updates the priorities. Due to this, when the user B having a lower priority comes closer to theMFP 1 than the user A having a higher priority who is moving toward theMFP 1, the priority of the user B can be changed to be higher than the priority of the user A, and finer control can be achieved. Moreover, in this case, such finer control can be achieved even when an inexpensive GPS that detects the positional information in a two-dimensional range is used as the GPS 33 of the portableterminal device 2. - That is, for example, it is assumed that the
MFP 1 is arranged on the first floor of a house, the user A is positioned on the fiftieth floor of the same house, and the user B is positioned on the third floor of the same house. In this case, based on three-dimensional positional information, the user B positioned on the third floor is closer to theMFP 1 placed on the first floor than the user A positioned on the fiftieth floor. However, with the GPS that has difficulty in detecting the positional information other than within the two-dimensional range, the distance between the user A and theMFP 1 and the distance between the user B and theMFP 1 are detected to be substantially the same. Even in such a case, when the positional information is periodically acquired as in the information processing system according to the embodiment, it can be detected that the user A is closer to theMFP 1 than the user B at the time when the user A goes down to the first floor from the fiftieth floor using an elevator and starts to walk toward theMFP 1, for example, and the priorities can be replaced with each other. - In this example, the portable
terminal device 2 that has transmitted the print job periodically detects the positional information of itself and transmits it to theMFP 1. However, the portableterminal device 2 may be configured to transmit the positional information of itself when having received a transmission request of the positional information from theMFP 1. Also in this case, the same effect as described above can be obtained. - The following describes the information processing system according to a second embodiment of the present invention. In the information processing system according to the first embodiment described above, the
MFP 1 directly communicates with the portableterminal device 2. On the other hand, in the information processing system according to the second embodiment, theMFP 1 communicates with the portableterminal device 2 via a server device. -
FIG. 10 is a system configuration diagram of the information processing system according to the second embodiment. As illustrated inFIG. 10 , in the information processing system according to the second embodiment, aserver device 50 is provided on thenetwork 4. Theserver device 50 mediates the communication between theMFP 1 and the portableterminal device 2. -
FIG. 11 is a hardware configuration diagram of theserver device 50. As illustrated inFIG. 11 , theserver device 50 has a configuration similar to that of a typical personal computer device. Theserver device 50 includes a communication unit 51, a ROM 52, aRAM 53, a CPU 54, and anHDD 55. From the communication unit 51 to theHDD 55 are connected to each other via a bus line 56. TheHDD 55 stores a printing processing program for theserver device 50. The CPU 54 operates according to the printing processing program stored in theHDD 55 to mediate the communication between theMFP 1 and the portableterminal device 2. - Specifically, the CPU 54 of the
server device 50 receives the print job transmitted from the portableterminal device 2, and transmits the print job to theMFP 1. The CPU 54 of theserver device 50 also receives the positional information that is periodically detected and transmitted by the portableterminal device 2 that has transmitted the print job, and transmits the positional information to theMFP 1. In a case in which the portableterminal device 2 is configured to transmit the present position of itself when theMFP 1 has made a request for acquiring the present position, the CPU 54 of theserver device 50 transmits the request for acquiring the present position from theMFP 1 to the portableterminal device 2. The CPU 54 of theserver device 50 transmits the positional information transmitted from the portableterminal device 2 in response to the request for acquiring the present position to theMFP 1. - In this way, even with the configuration in which the
MFP 1 communicates with the portableterminal device 2 via theserver device 50, the same effect as the first embodiment can be obtained. - First Modification
- The following describes a first modification of the information processing system according to each of the embodiments described above. In each of the embodiments described above, all the print jobs stored in the
job DB 29 are caused to be determination targets of priority replacement processing. On the other hand, in the information processing system according to the first modification, the print job in which the distance L between theMFP 1 and the portableterminal device 2 of the sender of the print job is equal to or larger than a certain distance is caused to be the determination target of the priority replacement processing to perform priority replacement processing. Due to this, the number of operations for the priority replacement processing can be reduced, and a burden on thereplacement processing unit 25 can be reduced. - Specifically, if the
check unit 21 determines that the number of the print jobs stored in thejob DB 29 is equal to or larger than 2 at Step S21 in the flowchart inFIG. 9 , thereplacement processing unit 25 calculates the distance L between theMFP 1 and the portableterminal device 2 of the sender of each print job. - When the distance L between the portable
terminal device 2 and theMFP 1 is short such that the distance between the portableterminal device 2 and theMFP 1 is, for example, equal to or smaller than 2 m (when the distance L is equal to or smaller than a certain distance), the sender of the print job is positioned near theMFP 1. The printed matter corresponding to the print job is highly likely to be collected by the sender in a short time. Due to this, thereplacement processing unit 25 performs the priority replacement processing using, as the determination target of the priority replacement processing, the print job of the portableterminal device 2 the distance L of which from theMFP 1 is equal to or larger than a certain distance. In other words, thereplacement processing unit 25 excludes, from the determination target of the priority replacement processing, the print job of the portableterminal device 2 the distance L of which from theMFP 1 is equal to or smaller than a certain distance. Thereplacement processing unit 25 then performs the replacement processing described above on the other print jobs remained after the exclusion. - Due to this, the number of operations for the priority replacement processing can be reduced, a burden on the
replacement processing unit 25 can be reduced, and the same effect as the embodiments described above can be obtained. - Second Modification
- The following describes a second modification of the information processing system according to each of the embodiments described above. In the example of the information processing system according to each of the embodiments and the modification, the priority replacement processing is performed in units of print jobs. On the other hand, in the example of the information processing system according to the second modification, the priority replacement processing is performed on the print job in units of pages.
- That is, in a case of the information processing system according to the second modification, when the print job is being executed, the replacement determination of a priority described with reference to
FIG. 7 is performed on the print job currently being executed and the print job having the highest priority in the print job queue (the print job having the first priority). If it is determined that the print job being executed should be replaced with the print job having the first priority in the replacement determination (if it is determined that the print job having the first priority should be executed rather than the print job being executed), thereplacement processing unit 25 temporarily stops the print job being executed, and stores the print job in a print job interruption stack provided in theRAM 18. TheCPU 16 then controls execution of the print job having the first priority instead. - Next, after the print job having the first priority is completed, the
CPU 16 restarts the print job in the midst of execution that has been stored in the print job interruption stack. In short, the print job being executed is temporarily stopped and the other print job is executed, that is, the printing process can be performed while replacing the priorities of the print jobs in units of pages. - In this case, when the printed matter of the interruption printing is ejected onto a paper ejection tray on which the printed matter of the print job temporarily stopped has been ejected, the printed matter of the print job temporarily stopped and the printed matter of the interruption printing are mixed on the paper ejection tray, and the user cannot easily collect the printed matter.
- Due to this, the
CPU 16 uses the positional information representing the present position of the portableterminal device 2 to determine the distance between the user of the interruption printing and theMFP 1. When the distance between the user of the interruption printing and theMFP 1 becomes equal to or smaller than a distance at which the user of the interruption printing can collect the printed matter of the interruption printing, theCPU 16 determines that the printed matter of the interruption printing is collected by the user of the interruption printing and restarts the print job that has been temporarily stopped. Thus, the printed matter of the print job that has been temporarily stopped is prevented from being mixed with the printed matter of the interruption printing. - The flowcharts of
FIG. 12 andFIG. 14 illustrate such a procedure of replacement processing of priorities in units of pages.FIG. 12 is a flowchart illustrating a procedure of processing for determining whether to replace the print job being executed with the print job having the first priority that is stored in the print job queue. The flowchart inFIG. 12 is started when the print job is started to be executed, and the process starts from Step S31. - At Step S31, the
replacement processing unit 25 determines the number of print job queues stored in thejob DB 29 in theRAM 18 described above with reference toFIG. 5 . If the number of print job queues stored in thejob DB 29 is equal to or larger than 1 (Yes at Step S31), the process proceeds to Step S32. On the other hand, if the number of print job queues stored in thejob DB 29 is less than 1 (=the number of print job queues is 0: No at Step S31), any print job other than the print job currently being executed is not present, so that theCPU 16 ends the process of the flowchart inFIG. 12 as it is. - At Step S32, the collection
time calculation unit 24 calculates the collection time for the printed matter corresponding to the print job having the first priority (the print job having the highest priority) and the collection time for the printed matter of the print job currently being executed. Thereplacement processing unit 25 determines whether the collection time for the printed matter corresponding to the print job having the first priority is shorter than the collection time for the printed matter of the print job currently being executed. That is, at Step S32, thereplacement processing unit 25 determines whether the printed matter corresponding to the print job having the first priority will be collected before the print job currently being executed is completed. If the print job currently being executed will be completed before the printed matter corresponding to the print job having the first priority is collected (No at Step S32), theCPU 16 ends the process of the flowchart inFIG. 12 as it is. On the other hand, if the printed matter corresponding to the print job having the first priority is estimated to be collected before the print job currently being executed is completed (Yes at Step S32), the process proceeds to Step S33. - Next, at Step S33, the
replacement processing unit 25 determines whether the user who comes to collect the printed matter of the print job currently being executed can immediately collect the printed matter even when the print job currently being executed is temporarily stopped and interrupted by the print job having the first priority to be executed. If it is determined that the user will be made to wait (No at Step S33), theCPU 16 ends the process of the flowchart inFIG. 12 as it is. On the other hand, if it is determined that the user will not be made to wait (Yes at Step S33), the process proceeds to Step S34. - At Step S34, the
replacement processing unit 25 temporarily stops the print job currently being executed, and executes the interrupting print job having the first priority. Thus, the entire process of the flowchart inFIG. 12 is ended.FIG. 13 schematically illustrates such interruption printing. InFIG. 13 , the print job represented by a circle of a dotted line is the print job currently being executed. To perform interruption printing, thereplacement processing unit 25 temporarily stops the print job currently being executed, and stores the print job in a printjob interruption stack 61 that is arranged in a storage unit such as theRAM 18 and stores the print job in a Last In First Out (LIFO) format. Thereplacement processing unit 25 acquires a first print job having the first priority from the printjob interruption stack 61 in place of the stored print job. Accordingly, the execution of the print job currently being executed is temporarily stopped, and the first print job becomes the print job to be executed. - The
CPU 16 executes the replaced first print job. After the first print job is completed, the print job temporarily stopped that has been stored in the printjob interruption stack 61 is read out and restarted. Thus, the printing processing can be performed while replacing the priorities of the print jobs in units of pages, and print waiting time for the first print job can be further reduced. -
FIG. 14 is a flowchart illustrating a procedure for restarting the print job that has been temporarily stopped after the interruption printing is completed. The flowchart inFIG. 14 is started when the interruption printing is completed, and the process starts from Step S41. At Step S41, theCPU 16 determines whether the print job being executed is present. That is, at Step S41, theCPU 16 determines whether the print job of the interruption printing is being executed. If the print job of the interruption printing is being executed (Yes at Step S41), the flowchart inFIG. 14 is ended as it is. On the other hand, if the print job of the interruption printing is completed (No at Step S41), the process proceeds to Step S42. - At Step S42, the
CPU 16 determines the number of print job queues stored in the printjob interruption stack 61. When one or more print job queues are stored in the printjob interruption stack 61, the print job that has been temporarily stopped is stored in the printjob interruption stack 61. Thus, when the number of print job queues stored in the printjob interruption stack 61 is equal to or larger than 1 (Yes at Step S42), theCPU 16 advances the process to Step S43. - On the other hand, when the number of print job queues stored in the print
job interruption stack 61 is less than 1 (=when the number of print job queues is 0: No at Step S31), the print job other than the print job currently being executed is not present. Accordingly, theCPU 16 ends the process of the flowchart inFIG. 12 as it is. - At Step S43, the
CPU 16 determines whether there is a paper ejection tray (empty tray) onto which the ejected printed matter is currently not present, the paper ejection tray being different from the paper ejection tray onto which the printed matter of the interruption printing has been ejected. That is, in this example, theMFP 1 includes a plurality of paper ejection trays. In a case of an MFP including only one paper ejection tray, the process at Step S43 is skipped. If the empty tray is present (Yes at Step S43), the process proceeds to Step S46. - At Step S46, the
CPU 16 acquires the print job temporarily stopped that has been stored in the printjob interruption stack 61 and restarts the print job. TheCPU 16 controls a paper ejection mechanism so that the printed matter of the restarted print job will be ejected onto the empty tray detected at Step S43. Due to this, the printed matter of the interruption printing can be prevented from being mixed with the printed matter of the print job the execution of which has been temporarily stopped, on the same paper ejection tray. - The
CPU 16 may control the paper ejection mechanism to detect the paper ejection tray used when the execution of the print job was temporarily stopped as the empty tray described above, and cause the printed matter of the restarted print job to be ejected thereon. - On the other hand, in a case in which only one paper ejection tray is arranged, or although a plurality of paper ejection trays are arranged, the printed matter is present on all of the paper ejection trays other than the paper ejection tray on which the printed matter of the interruption printing has been ejected (if the printed matter is not collected: No at Step S43), the
CPU 16 advances the process to Step S44. At Step S44, theCPU 16 determines whether a time-out function of waiting for collection of the printed matter is set to be ON. Specifically, the information processing system according to the second modification has the time-out function of waiting for collection of the printed matter to wait for restart of the print job that has been temporarily stopped until the collection time at which the printed matter of the interruption printing is collected by the user. The time-out function can be set by an administrator of theMFP 1 via a setting menu. By way of example, the time-out function is set to be ON in a default setting. The setting information of the time-out function is stored in the storage unit such as theRAM 18, theHDD 19, and the ROM 17 illustrated inFIG. 1 . At Step S44, theCPU 16 refers to the setting information stored in the storage unit to determine whether the time-out function is set to be ON. - If the time-out function is set to be ON (Yes at Step S44), the process proceeds to Step S47, and the
CPU 16 waits for restart of the print job that has been temporarily stopped until the collection time calculated by the collectiontime calculation unit 24 at which the printed matter of the interruption printing will be collected by the user. When the collection time has been reached, theCPU 16 determines that the printed matter of the interruption printing is collected by the user, and restarts, at Step S46, the print job that has been temporarily stopped. - On the other hand, if the time-out function is not set to be ON (No at Step S44), the
CPU 16 determines whether the distance between theMFP 1 and the present position of the portableterminal device 2 of the user of the interruption printing acquired by theposition acquisition unit 22 becomes the distance at which the printed matter of the interruption printing can be collected. That is, when the distance between the user of the interruption printing and theMFP 1 is, for example, equal to or smaller than 30 cm, it can be said that the user can collect the printed matter of the interruption printing from the paper ejection tray of theMFP 1 at that distance. Thus, theCPU 16 determines that the printed matter has been collected when the distance between the user of the interruption printing and theMFP 1 has become equal to or smaller than the distance at which the user can collect the printed matter of the interruption printing (Yes at Step S45), and restarts the print job that has been temporarily stopped at Step S46. - As is obvious from the above description, the information processing system according to the second modification temporarily stops the print job being executed when having detected the print job in which the collection time for the printed matter is estimated to be earlier than the collection time for the printed matter of the print job being executed. Then interruption printing of the print job in which the collection time for the printed matter is estimated to be earlier is performed, and the print job that has been temporarily stopped is restarted after the interruption printing is completed. Accordingly, the printing processing can be performed while replacing the priorities of the print jobs in units of pages, the print waiting time for the user can be further reduced, and the same effect as the embodiments described above can be obtained.
- When the time-out function is set to be ON, the information processing system waits for restart of the print job that has been temporarily stopped until the collection time at which the printed matter of the interruption printing will be collected by the user. When the collection time has passed, the information processing system determines that the printed matter of the interruption printing has been collected by the user, and restarts the print job that has been temporarily stopped. Accordingly, the print job that has been temporarily stopped can be restarted after the printed matter of the interruption printing has been collected by the user, and the printed matter of the interruption printing can be prevented from being mixed with the printed matter of the print job that has been temporarily stopped. That is, the user can collect the printed matter of the preceding print job and the printed matter of the interruption printing clearly separately from each other.
- In a case in which the time-out function is set to be OFF, when the distance between the user of the interruption printing and the
MFP 1 has become equal to or smaller than the distance at which the user can collect the printed matter of the interruption printing from the paper ejection tray of theMFP 1, the information processing system determines that the printed matter of the interruption printing is collected by the user, and restarts the print job that has been temporarily stopped. Accordingly, the print job that has been temporarily stopped can be restarted after the printed matter of the interruption printing is collected by the user, and the printed matter of the interruption printing can be prevented from being mixed with the printed matter of the print job that has been temporarily stopped. That is, the user can collect the printed matter of the preceding print job and the printed matter of the interruption printing clearly separately from each other. - The printed matter of the restarted print job is ejected onto the empty tray. Accordingly, the printed matter of the interruption printing can be prevented from being mixed with the printed matter of the print job that has been temporarily stopped, and the user can collect the printed matter of the preceding print job and the printed matter of the interruption printing clearly separately from each other.
- The embodiments and the modifications described above are exemplary only, and are not intended to limit the scope of the present invention. These novel embodiments and modifications can be implemented in other various forms. The embodiments and the modifications can be variously omitted, replaced, and modified without departing from the gist of the present invention.
- For example, the information processing system may continuously perform the replacement determination during execution of the print job, may perform priority replacement processing by interrupting the print job being executed if the condition described with reference to
FIG. 7 is satisfied, and may process the print job according to the replaced priorities (interruption). In this case, each print job is processed as interruption such that the print job having a lower priority is executed during printing of the print job having a higher priority, for example. Accordingly, the print job can be executed while performing finer replacement processing. - According to an embodiment, efficiency of information output can be enhanced.
- According to an aspect, an information processing system includes: a terminal device; and an information processing device. The terminal device detects and transmits a current position at predetermined timings after transmitting an information processing request.
